Characterization Of The Interaction Of Titanium With Different Elements

Titanium is an active metallic element, which can have certain interaction with most of the elements in the periodic table. I. I. Kornilov divided the elements in the periodic table into 4 groups according to the characteristics of the interaction of each element with titanium.

The first group, is with a titanium or β titanium to form a continuous solid solution of elements, this group has 10 elements, they are titanium in the periodic table are close neighbors, and its atomic radius and titanium atomic radius of the difference between most of the not more than 8%, these elements are scandium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum, tungsten and uranium. Among them, zirconium, hafnium and titanium homologous elements and titanium form α and β-continuous solid solution, the remaining eight elements and titanium only form β-continuous solid solution.

The second group consists of elements that form limited solid solutions with titanium, certain metal compounds and covalent bond compounds. There are more than 60 elements in this group, excluding rare-earth metals, and more than 40 elements. The position of this group of elements in the periodic table is farther away from titanium than that of the first group of elements, and there is also a big difference between them and titanium in terms of chemical properties, so they tend to form compounds with titanium; however, some of their atomic radii are similar to those of titanium, and some of them are much smaller than titanium. This makes it possible for them to form a limited solid solution with titanium, this group of elements more important to the study of titanium alloys are: manganese, iron, cobalt, nickel, copper, boron, aluminum, gallium, carbon, silicon, tin, nitrogen, bismuth, oxygen, hydrogen and so on.

The third group, and titanium does not form a solid solution, but the formation of different types of covalent compounds and ionic compounds of the elements, this group of nine elements, they are located on the right side of the periodic table, the halogen and titanium form ionic compounds, such as TiCl4, TiI4 and so on.

The fourth group, is not interact with titanium elements, this group of elements including alkali metals and alkaline earth metals (except beryllium), they are located in the leftmost side of the periodic element, plus noble gases, a total of 17 elements.
